IMPROVEMENT IN CAPS FOR METALLIC CANS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, GEORGE H. PERKINS, of the city of Brooklyn, in thecounty of Kings, and State of :New York, have invented a new and nsel'nl Improvement in Month-Pieces or Caps for Metallic or other Cans; and I hereby declare the followin, ,r to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which are lettered to correspond with and form a part of the specification.

To enable the public tonnderstand the nature of my said invention, and those who are skilled in the tinsmixhs art to construct the same, I will describe it, as follows, to wit:

Figure i isa perspective drawing of the top of a tin or olherean, having m improved mouth-piece or cap. which consists of three distinct parts, A, B, and C, arranged as shown 'more clearly in Figure 3, which is, a vertical section of my in nproved moutlepiece or cap, A, when soldered in the top of the can.

Figure 2 is also a vertical section of a square can, having my compound mouth-piece A and B, with the male screw-cap C removed, in order to show the projecting upper edge B of the soft, thin sheet metal which constitutes the plug of the vessel. or can, and which is supported on the inside by a more rigid `me lallic screw-ring, A, which is soldered to the soft sheet metal at the lower part thereof, and which is iirther secured by turning the upper edge B ofthe soft, thin sheet metal down upon the top of the ring A, as shown at tig. 3, preparatory to receiving the male. sere\\'plug0.

By the useoi'an additional scre\\'ring, A, heide of the thin sheet metallic plug, I am enabled to use much thinner sheet metal for the. inside cap or ping B, so that it can easily be cut away with an or..i.a.ry pen-knife, without breaking the same, as the ring A is sufficiently firm to receive an ordinary wooden spigot or plug, and to cut a thread upon the same, thereby holding it in its place without leakage ot' the contents of the can.

Aor nozzle of the can, as is the case with the English nozzle. y y

Theren'e, I do not claim forming screw-thremis in or upon sheetmetal nozzles for cans; neitherdo Iclaim soft, thin sheet-brass for the nozzle of a can; but by my arrangement I am enabled to me a much lighter inside cap, B, formed in onepieee of the thinnest sheetv brass, or even softer metal, such 'as vlead or zinc, and yet retain all the rigidity and durability of any other apparatus ofthe kind, by simply ara-urging the throat of the can belowthe line of the vtop thereof', and inserting the rigid screw-ring A, which constitutes the novelty oi' my invention, and may be made of brass, or any other suitable metal that will ont a. thread upon the spigot or faucet when inserted into the opening' of the can, and thus prevent any-leakage of its contents,

excepting through the. faucet. olherefore,

What I claim asinovel and useful, and what I wish to secure by Letters Patent ofthe Unit-ed States, is-

The combination ofthe month-piece orring A, sheetmetal cap or ping B, and male screw-cap O, constructed substantially as described.

In testimony whereof I hereunto subscribe my name in the presence of two witnesses.

GEORGE H. PERKINS.
